# hi
|
|
this showcases my worst idea yet; *extending markdown with inline javascript*
|
|
|
|
due to obvious reasons it's disabled by default, and can be enabled with `-emp`
|
|
|
|
the examples are by no means correct, they're as much of a joke as this feature itself
|
|
|
|
|
|
### sub-header
|
|
nothing special about this one
|
|
|
|
|
|
## except/
|
|
this one becomes a hyperlink to ./except/ thanks to
|
|
* the `copyparty_pre` plugin at the end of this file
|
|
* which is invoked as a markdown filter every time the document is modified
|
|
* which looks for headers ending with a `/` and erwrites all headers below that
|
|
|
|
it is a passthrough to the markdown extension api, see https://marked.js.org/using_pro
|
|
|
|
in addition to the markdown extension functions, `ctor` will be called on document init
|
|
|
|
|
|
### these/
|
|
and this one becomes ./except/these/
|
|
|
|
|
|
#### ones.md
|
|
finally ./except/these/ones.md
|
|
|
|
|
|
### also-this.md
|
|
whic hshoud be ./except/also-this.md
|
|
|
|
|
|
|
|
|
|
# ok
|
|
now for another extension type, `copyparty_post` which is called to manipulate the generated dom instead
|
|
|
|
`copyparty_post` can have the following functions, all optional
|
|
* `ctor` is called on document init
|
|
* `render` is called when the dom is done but still in-memory
|
|
* `render2` is called with the live browser dom as-displayed
|
|
|
|
## post example
|
|
|
|
the values in the `ex:` columns are linkified to `example.com/$value`
|
|
|
|
| ex:foo | bar | ex:baz |
|
|
| ------------ | -------- | ------ |
|
|
| asdf | nice | fgsfds |
|
|
| more one row | hi hello | aaa |
|
|
|
|
and the table can be sorted by clicking the headers
|
|
|
|
the difference is that with `copyparty_pre` you'll probably break various copyparty features but if you use `copyparty_post` then future copyparty versions will probably break you

# heres the plugins
|
|
if there is anything below ths line in the preview then the plugin feature is disabled (good)
